  1. 21. Spacetime as a Hamiltonian Orbit and Geroch's Theorem on the Existence of Fermions

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Viktor Bergstedt; [2020]
    Keywords : 3 1; ADM; black hole; canonical quantization; Cauchy surface; causality; differential geometry; Einstein-Hilbert action; general relativity; Geroch; globally hyperbolic; Hamilton s equations; numerical relativity; parallelizable; SL 2; C ; spacetime; spinor; spin structure; SO 1; 3 ; Stiefel-Whitney class; tetrad; topology;

    Abstract : Over a century since its inception, general relativity continues to lie at the heart of some of the most researched topics in theoretical physics. It seems likely that the coveted solutions to problems like quantum gravity are to be found in an extension of general relativity, one which may only be visible in an alternate formulation of the theory.

  3. 22. Application of Topic Models for Test Case Selection : A comparison of similarity-based selection techniques

    University essay from Linköpings universitet/Programvara och system

    Author : Kim Askling; [2019]
    Keywords : test automation; test case selection; machine learning; latent dirichlet allocation; differential evolution; testautomation; testfallsselektion; maskininlärning; latent dirichlet allocation; differentiell evolution;

    Abstract : Regression testing is just as important for the quality assurance of a system, as it is time consuming. Several techniques exist with the purpose of lowering the execution times of test suites and provide faster feedback to the developers, examples are ones based on transition-models or string-distances.

  4. 23. An Analysis of Including the Evolution Law for the Serial Element in the Musculoskeletal Modelling

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Alexandra Roser; [2019]
    Keywords : biomechanical simulation; contraction dynamics; dissipation inequality; Hill-type muscle model; strain-energy function;

    Abstract : In the classic Hill model for muscle contraction, the split between the muscle and tendon is arbitrary and the problem lacks a unique solution. Instead of reformulating the problem to a differential-algebraic equation and solving for a set of initial conditions, a constant tendon length is commonly assumed in musculoskeletal simulation tools.

  5. 24. Detailed analysis of the chemical composition of stars harboring Earth-like planets

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Lorena Acuña Aguirre; [2019]
    Keywords : Physics and Astronomy;

    Abstract : Context. The planet-metallicity correlation for gaseous giants is widely accepted through spectroscopic studies. However, whether a similar correlation exists for terrestrial planets is a debated subject. READ MORE

  6. 25. Evolving Chemical Reaction Networks

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Elisabeth Degrand; [2019]
    Keywords : ;

    Abstract : One goal of synthetic biology is to implement useful functions with biochemical reactions, either by reprogramming living cells or programming artificial vesicles. In this perspective, we consider Chemical Reaction Networks (CRNs) as a programming language. READ MORE
